Aerobic fermentation biological treatment device and method for organic waste

Abstract

The invention discloses an aerobic fermentation biological treatment device and method for organic waste. The device comprises a kitchen waste preparation pretreatment device, an auxiliary material bin, a stirring machine, an organic waste biological treatment machine, a product deep processing device, a slag sorting device and a slag bin, wherein an outlet of the slag bin is communicated with the stirring machine. Small-particle materials screened out after aerobic fermentation treatment are put into the organic waste biological treatment machine for aerobic fermentation, and secondary utilization is achieved. Through secondary utilization of residues, the properties of materials to be fermented are improved, the number and quality of products are increased, waste is reduced, the efficiency of the organic waste biological treatment machine is improved, and comprehensive energy consumption and waste landfill cost are reduced. The porosity of a fermented material is increased, the volume and the specific surface area of a mixed material are increased, the contact area with the heat exchange surface of equipment is increased, the utilization rate of the equipment is improved, the aerobic equipment type fermentation effect is facilitated, the indexes of the calcium content and the phosphorus content of a product are improved, and the product quality is better.

Description

technical field [0001] The invention relates to the technical field of organic waste treatment, in particular to an organic waste aerobic fermentation biological treatment device and a method thereof. Background technique [0002] Organic waste biological processor is generally a device that uses high-temperature and high-speed aerobic fermentation technology to ferment organic waste to prepare microbial agents, soil conditioners and other products. [0003] The process of aerobic fermentation and biological treatment of organic waste is generally: put organic waste and auxiliary materials into the organic waste biological processor in a certain proportion, and add an appropriate amount of bacteria, under specific temperature, humidity, pressure and oxygen supply conditions, The microbial strains grow and reproduce rapidly, and the fermentation process is completed after a certain period of time to realize the resource utilization of organic waste. [0004] The products pro...

AI Technical Summary

Problems solved by technology

[0005] However, the treatment of the sieve residue will increase the processing cost and cause a low degree of resource utilization of organic waste. In addition, the surface of the slag phase will adhere to a large amount of post-fermentation products, which also causes a certain degree of waste.
